Description

[Technical field]

[0001] The present invention relates to a traverser for railway vehicles that comprises a base for mounting a vehicle bogie, the base having rails on which the vehicle bogie can run and a plurality of bogie stopping parts provided along the rails, and that transports the vehicle bogie stopped at the bogie stopping parts. [Background technology]

[0002] In inspection and repair depots where inspections, maintenance, etc. (hereinafter simply referred to as inspection and repair) of railway vehicles are carried out, multiple inspection and repair rails are laid parallel to each other on the floor of the inspection and repair depot, and a railway vehicle placed on one of the multiple inspection and repair rails may be traversed to another inspection and repair rail.

[0003] To perform this traverse, a railcar traverser is used, as disclosed in Patent Document 1. This railcar traverser has a base for mounting the railcar, and the base is provided with rails on which the railcar can run. Furthermore, it is movable in a direction perpendicular to the rail for inspection and repair.

[0004] Traversing using such a railcar traverser is performed as follows. For example, if a railcar is to be traversed from a first inspection / repair rail to a second inspection / repair rail laid parallel to the first inspection / repair rail, first, the rail of the railcar traverser and the first inspection / repair rail are aligned in the sleeper direction, and then the railcar is pulled from the first inspection / repair rail onto the base. The railcar pulled onto the base is made to run along the rail of the base and is stopped at a predetermined position on the base, completing the loading onto the base. After the railcar is loaded onto the base, the railcar traverser is moved in a direction perpendicular to the rail (hereinafter referred to as the lateral direction) to a position where the lateral positions of the rail of the railcar traverser and the second inspection / repair rail are aligned. Finally, the railcar is lowered from the base onto the second inspection / repair rail, completing the traverse.

[0005] In general, when inspecting a railcar, the car body and the bogie of the railcar to be inspected are separated, and then the inspection of the car body and the bogie are performed separately, so that only the bogie separated from the car body may be loaded onto the railcar traverser and traversed. In this case, for example, the base has a plurality of bogie stopping parts provided along the rail, and the bogie pulled into the base from the inspection rail is transported along the rail to the bogie stopping parts and stopped at the bogie stopping parts, and then the railcar traverser is moved laterally to perform the traverse.

[0006] [Patent Document 1] JP 2017-185905 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, the above-mentioned conventional techniques have the following problems. The vehicle bogie separated from the car body does not have power and cannot move on its own. Therefore, when transporting the vehicle bogie pulled into the base along the rail to the bogie stop, a worker must push the vehicle bogie to run along the rail. However, since the vehicle bogie is heavy, it is undesirable from a safety standpoint to run the vehicle bogie by hand. Therefore, there is a demand for a railway vehicle traverser that can automatically transport the vehicle bogie to the bogie stop.

[0008] For example, in an inspection and repair depot, a transport device that has power and can move along the inspection and repair rail using the power is arranged under the inspection and repair rail. The transport device holds a vehicle bogie and moves along the inspection and repair rail using its own power, causing the vehicle bogie to automatically run on the inspection and repair rail. In other words, the transport of the vehicle bogie can be performed automatically. By applying such a transport device having power to a railway vehicle traverser, it is considered that the railway vehicle traverser can also automatically transport a vehicle bogie pulled into the base to the bogie stop section.

[0009] However, the problem here is the space required to install the transport device. The transport device used in the inspection and maintenance depot described above is large in size because it has power. Therefore, it is necessary to provide a space (hereinafter referred to as the movement space) that allows such a transport device to move along the rail. Furthermore, the transport device that moves along the rail must be connected to a power source and a control device, and a space (hereinafter referred to as the wiring space) is required to route the wiring. In the inspection and maintenance depot, a pit with a depth of 500 to 600 mm is provided under the inspection and maintenance rail to ensure the movement space and the wiring space. However, since the base of the traverser for rail vehicles is generally about 200 mm thick, there is not enough space to provide a pit with a depth of 500 to 600 mm under the rail. In addition, it is not preferable to enlarge the traverser to provide the transport device and to deepen the pit for the traverser of the inspection and maintenance facility by another 500 to 600 mm from the viewpoint of installation costs and safety of the inspection and maintenance facility. Therefore, it is not possible to provide a transport device with the same power as that in the inspection and maintenance depot in the traverser for rail vehicles.

[0010] The present invention is intended to solve the above-mentioned problems, and aims to provide a traverser for railway vehicles that is equipped with a space-saving conveying device and can automatically run vehicle bogies along rails. [Means for solving the problem]

[0011] In order to solve the above problems, the traverser for a railway vehicle of the present invention has the following configuration: is. (1) A vehicle bogie is provided with a base for mounting the vehicle bogie, the base having a rail on which the vehicle bogie can run and a plurality of bogie stopping parts provided along the rail, and the vehicle bogie stopped at the bogie stopping parts is stopped at the bogie stopping parts. , along a traverse rail perpendicular to the rail In a traverser for transporting railway cars, On top of the base a transport device movable along the rail for running the vehicle bogie along the rail, the transport device including a wheel holding member for holding wheels of the vehicle bogie, the wheel holding member being movable between a first position for releasing the holding of the wheels and a second position for holding the wheels, the base being a support for moving the transport device along the rail, , fixed to the base First drive unit Place and front a wheel holding member of the transport device located at the carriage stop portion between the first position and the second position; , fixed to the carriage stop and a second drive device.

[0012] (2) a railway vehicle traverser for transporting the vehicle bogie stopped at the bogie stopping parts, the railway vehicle traverser comprising a base for mounting a vehicle bogie, the base comprising a rail on which the vehicle bogie can run and a plurality of bogie stopping parts provided along the rail, the railway vehicle traverser comprising a transport device movable along the rail for running the vehicle bogie along the rail, the transport device comprising a wheel holding member for holding wheels of the vehicle bogie, the wheel holding member being movable between a first position at which the holding of the wheels is released and a second position at which the wheels are held, the base comprising a first drive device for moving the transport device along the rail, and the bogie stopping parts comprising a second drive device for moving the wheel holding member of the transport device positioned at the bogie stopping parts between the first position and the second position, The second drive unit has an operating shaft capable of linear motion, the wheel holding member has an engagement portion that engages with the operating shaft, and when the conveying device is positioned at the cart stop portion, the engagement portion engages with the operating shaft, and this engagement enables the second drive unit to move the wheel holding member between the first position and the second position.

[0013] (3) In the railway vehicle traverser described in (1) or (2), the bogie stopping section is provided with a stopper device that positions the vehicle bogie, the stopper device is provided with a pair of wheel stop members arranged parallel to and facing the rail, each of the pair of wheel stop members is movable between a wheel stop position in the vicinity of the running surface of the rail so as to be able to come into contact with the wheels, and a retracted position in which the wheel stop members are retracted from the vicinity of the running surface of the rail so as to be unable to come into contact with the wheels, the stopper device is provided with an elastic member that biases each of the pair of wheel stop members to be positioned at the wheel stop position, and When a wheel of the vehicle bogie traveling on the rail comes into contact with one of the pair of wheel stop members from the side opposite to the side facing the other wheel stop member, the one wheel stop member is pressed by the wheel of the vehicle bogie heading toward the bogie stopping section, and is moved toward the retracted position against the elastic force of the elastic member, allowing the wheel to pass through the one wheel stop member; and when the wheel has passed through the one wheel stop member, the one wheel stop member returns to the wheel stop position due to the elastic force of the elastic member, and clamps the wheel together with the other wheel stop member, positioning the vehicle bogie at the bogie stopping section. Effect of the Invention

[0014] According to the railway vehicle traverser of the present invention, the transport device is moved along the rail by a first drive device provided on the base. Furthermore, the transport device has a wheel holding member for holding the wheels of the vehicle bogie, and the wheel holding member is moved between a first position where the wheel holding is released and a second position where the wheel is held by a second drive device provided on the bogie stop unit.

[0015] In other words, the conveying device itself does not have any power. Since the conveying device does not have power, the size of the conveying device can be reduced. Therefore, it is possible to minimize the space required for movement. Also, since the conveying device does not have power, it is not necessary to connect the conveying device to a power source or a control device. The power source and the control device can be connected to the first drive device provided on the base and the second drive device provided on the bogie stop unit, and since these do not move like the conveying device, it is possible to minimize the space required for wiring. By providing a space-saving conveying device that minimizes the space required for movement and wiring, the railway vehicle traverser can automatically run the vehicle bogie along the rails.

[0016] For example, if the base is equipped with four bogie stopping sections, arranged along the rail from the side where the vehicle bogie is pulled in, in the order of the first bogie stopping section, the second bogie stopping section, the third bogie stopping section, and the fourth bogie stopping section, the vehicle bogie pulled into the railway vehicle traverser can be automatically transported as follows.

[0017] First, the transport device with the wheel holding member positioned at the first position is kept waiting at the first bogie stopping section. Then, the vehicle bogie is pulled from the inspection and repair rail to the base and first stopped temporarily at the first bogie stopping section. In this state, the wheel holding member of the transport device is moved from the first position to the second position by the second drive device provided in the first bogie stopping section. As a result, the wheel holding member holds the wheels of the vehicle bogie. In other words, the transport device is in a state where it holds the vehicle bogie. When the transport device is moved along the rail to the fourth bogie stopping section by the first drive device provided in the base while the transport device is holding the vehicle bogie, the vehicle bogie runs along the rail with the movement of the transport device and is transported to the fourth bogie stopping section. After the transport device stops at the fourth bogie stopping section, the wheel holding member of the transport device is moved from the second position to the first position by the second drive device provided in the fourth bogie stopping section, and the holding of the wheels is released, and the transport of the vehicle bogie is completed. Once the transport device has completed its transportation, it can be returned to the first bogie stopping section by the first drive device, and the second vehicle bogie can then be transported to the third bogie stopping section.Furthermore, after the transport of the second vehicle bogie has been completed, the third vehicle bogie can be similarly transported to the second bogie stopping section.

[0018] As described above, if it becomes possible to automatically run vehicle bogies along the rails, there will be no need to use human labor to transport the vehicle bogies on railway vehicle traversers, thereby ensuring the safety of workers. [Brief description of the drawings]

[0020] An embodiment of a railway vehicle traverser according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a railway vehicle traverser 100 according to this embodiment. FIG. 2 is a side view of a railway vehicle traverser 100 according to this embodiment.

FIG. 5 is a cross-sectional view taken along line CC in FIG. 4. FIG. 6 is a partially enlarged view of the fourth bogie stop part 115D in FIG. 3, showing a state in which the wheel holding member 32 is in the second position. FIG. 7 is a cross-sectional view taken along line DD in FIG. 6. FIG. 8 is a cross-sectional view taken along line BB in FIG. 3, showing the configuration of the first drive device.

[0021] As shown in Figures 1 and 2, the railway vehicle traverser 100 is composed of a base 101, side walls 102, and a roof 103. End openings 105 are provided at both ends in the longitudinal direction (left and right direction in Figure 1), and a railway vehicle 10 or a vehicle bogie 20 can be loaded onto the railway vehicle traverser 100 from the end openings 105.

[0022] The base 101 is a bogie body in which a floor plate is joined to a frame body formed in a substantially rectangular shape, and is provided with a plurality of traverse wheels 109 at the bottom. The traverse wheels 109 are provided to run on traverse rails 150 laid within the inspection and repair depot site, and can self-propel the railway vehicle traverser 100 by connecting them to a motor (not shown). The traverse rails 150 are provided in a direction perpendicular to a plurality of inspection and repair rails (not shown) provided within the facility, and the railway vehicle 10 or vehicle bogie 20 mounted on the railway vehicle traverser 100 can be traversed from one of the plurality of inspection and repair rails to another inspection and repair rail.

[0023] As shown in Fig. 3, a pair of rails 107A, 107B on which the railway vehicle 10 or the vehicle bogie 20 can run are arranged on the base 101. The upper surfaces of the rails 107A, 107B form a running surface 1071 (see Figs. 5 and 7) on which the railway vehicle 10 or the vehicle bogie 20 runs. This running surface 1071 is at approximately the same height as the floor surface 101a of the base 101. Meanwhile, the surface of the base 101 sandwiched between the rails 107A, 107B forms a step surface 101b that is lower in height than the floor surface 101a and the running surface 1071. This height difference is approximately 50 mm.

[0024] The railway vehicle 10 or the vehicle bogie 20 is loaded onto the railway vehicle traverser 100 by drawing the railway vehicle 10 or the vehicle bogie 20 into the base 101 from the end opening 105, running the railway vehicle 10 or the vehicle bogie 20 that has been drawn into the base 101 on the rails 107A, 107B (running surface 1071), and stopping it at a prescribed stopping position. When loading, the railway vehicle 10 is equipped with a temporary bogie that has power, so it can move on its own, but the vehicle bogie 20 is not equipped with a self-propelling means.

[0025] A tongue rail 108 is disposed on the extension of the rails 107A and 107B. The tongue rail 108 is tapered so that the thickness in the height direction gradually decreases toward the tip, and is disposed so as to overlap the inspection and repair rail (not shown). Therefore, the tongue rail 108 forms an upward slope from the inspection and repair rail toward the rails 107A and 107B, and the railway car 10 or the vehicle bogie 20 can be smoothly pulled from the inspection and repair rail to the rails 107A and 107B.

[0026] Furthermore, the base 101 includes a pair of conveyor rails 110A, 110B parallel to the rails 107A, 107B, a conveyor guide rail 111 parallel to the rails 107A, 107B, a conveyor device 30 that travels on the conveyor rails 110A, 110B while being guided by the conveyor guide rail 111, a first drive device for driving the conveyor device 30, which is composed of a motor 113 and a first loop chain 114, and four carriage stop parts 115 arranged at equal intervals along the rails 107A, 107B. The carriage stop parts 115 are, in order from the motor 113 side, a first carriage stop part 115A, a second carriage stop part 115B, a third carriage stop part 115C, and a fourth carriage stop part 115D. In addition, in the following, when describing matters common to the first carriage stopping portion 115A, the second carriage stopping portion 115B, the third carriage stopping portion 115C, and the fourth carriage stopping portion 115D, they will be simply referred to as carriage stopping portion 115.

[0027] The transport rails 110A, 110B are laid by being fixed to the step surface 101b with bolts or the like, and have a length from the end of the first carriage stop portion 115A on the motor 113 side to the end of the fourth carriage stop portion 115D on the end opening 105 side. The upper surfaces of the transport rails 110A, 110B are running surfaces 1101 (see Figs. 5 and 7) on which the transport device 30 runs, and the height of this running surface 1101 from the step surface 101b is about half the height of the running surfaces 1071 of the rails 107A, 107B.

[0028] The transport guide rail 111 is laid at a position sandwiched between the rail 107A and the transport rail 110A on the step surface 101b from the center of the first cart stopping portion 115A in the track direction to the center of the fourth cart stopping portion 115D in the track direction.

[0029] The conveyance guide rails 111 are made up of three fixed guide rails 1111 and four movable guide rails 1112. Each of the four movable guide rails 1112 is disposed in the center of the carriage stopping section 115 in the track direction, and each of the three fixed guide rails 1111 is laid so as to be sandwiched between the movable guide rails 1112.

[0030] The fixed guide rail 1111 is fixed to the step surface 101b with bolts or the like. A first guide groove 1111a (see Figs. 4 and 6) for guiding the transport device 30 is drilled in the upper surface of the fixed guide rail 1111. This first guide groove 1111a penetrates the fixed guide rail 1111 from one end face to the other end face in the longitudinal direction, so that the cross section of the fixed guide rail 1111 in the sleeper direction is concave-shaped.

[0031] The movable guide rail 1112 is connected to a rod 1161 of a first air cylinder 116 described later via a coupling member 1162 (see Figs. 4 to 7), and is capable of sliding in the sleeper direction of the rails 107A and 107B by the operation of the first air cylinder 116. This sliding movement is performed between a first position shown in Figs. 4 and 5 and a second position shown in Figs. 6 and 7. A second guide groove 1112a is formed in the upper surface of the movable guide rail 1112. The second guide groove 1112a penetrates the movable guide rail 1112 in the track direction, and the cross section of the movable guide rail 1112 in the sleeper direction is concave-shaped.

[0032] The width and depth of the second guide groove 1112a are the same as those of the first guide groove 1111a of the fixed guide rail 1111. When the movable guide rail 1112 is in the first position, the side wall 1112b of the second guide groove 1112a on the conveying device 30 side coincides with the side surface 1111b of the fixed guide rail 1111 on the opposite side to the conveying device 30 side in the lateral direction, and the first guide groove 1111a and the second guide groove 1112a are positioned alternately. When the movable guide rail 1112 is in the second position, the first guide groove 1111a and the second guide groove 1112a coincide with each other in the width direction, so that a continuous groove is formed by the first guide groove 1111a and the second guide groove 1112a.

[0033] The bogie stopping portion 115 is a stopping position on the base 101 when the vehicle bogie 20 traverses. As shown in Fig. 4 to Fig. 7, the bogie stopping portion 115 includes a first air cylinder 116 (an example of a second driving device), position detection sensors 117A, 117B, and 117C for detecting the position of the conveyance device 30, and a bogie detection sensor 118 for detecting whether the vehicle bogie 20 is stopped at the bogie stopping portion 115.

[0034] The first air cylinder 116 is fixed to the step surface 101b by a support member 1163 between the rail 107A and the conveying guide rail 111 and at the center of the carriage stop part 115 in the track direction. The first air cylinder 116 has a rod 1161 (one example of a motion axis) that moves linearly in the lateral direction of the rails 107A and 107B, and a movable guide rail 1112 is connected to the tip of the rod 1161 via a connecting member 1162. Therefore, as the rod 1161 moves linearly, the movable guide rail 1112 is slid between the first position and the second position described above.

[0035] The position detection sensors 117A, 117B, and 117C are fixed to the step surface 101b between the rail 107A and the conveying guide rail 111, lined up in the track direction. The position detection sensors 117A, 117B, and 117C are, for example, limit switches, and each has an actuator 1171. When the actuator 1171 is operated, the position detection sensors 117A, 117B, and 117C detect the position of the conveying device 30.

[0036] The roles of the position detection sensors 117A, 117B, and 117C will be described. When the conveying device 30 traveling from the first carriage stop section 115A side is to be stopped at the second carriage stop section 115B, the third carriage stop section 115C, or the fourth carriage stop section 115D, when the position detection sensor 117A detects the conveying device 30, the motor 113 is controlled by a control device (not shown) provided on the side wall section 102, for example, and the conveying device 30 is decelerated. Furthermore, when the position detection sensor 117B detects the conveying device 30, the motor 113 is stopped by the control device, and the conveying device 30 is stopped at the second carriage stop section 115B, the third carriage stop section 115C, or the fourth carriage stop section 115D. Then, with regard to the fourth carriage stop section 115D, when the conveying device 30 has passed the stop position, the position detection sensor 117C detects the conveying device 30. In other words, the position detection sensor 117C is a sensor for preventing overshooting.

[0037] Conversely, when the conveying device 30 traveling from the fourth carriage stopping section 115D side is to be stopped at the first carriage stopping section 115A, the second carriage stopping section 115B, or the third carriage stopping section 115C, when the position detection sensor 117C detects the conveying device 30, the conveying device 30 is decelerated, and when the position detection sensor 117B detects the conveying device 30, the conveying device 30 is stopped. As for the first carriage stopping section 115A, when the conveying device 30 has passed the stop position, the position detection sensor 117A detects the conveying device 30.

[0038] The cart detection sensor 118 is disposed on the rear side of the step surface 101b which cannot be seen from outside the base 101. A base portion 1011 is provided on the rear side of the step surface 101b, and the cart detection sensor 118 is fixed via a fixing bracket 1013 to a support member 1012 which is erected on the base portion 1011.

[0039] The bogie detection sensor 118 is, for example, a limit switch, and has an actuator 1181. When this actuator 1181 is operated, the bogie detection sensor 118 detects that the vehicle bogie 20 is stopped by the bogie stopping portion 115.

[0040] More specifically, this detection is performed by a lever member 119 located between the bogie detection sensor 118 and the rail 107A. The lever member 119 is rotatably held by the support member 1012 through a rotating shaft 1014. The end of the lever member 119 on the rail 107A side is a wheel contact portion 119a, and the other end is an actuator operation portion 119b, and the vehicle bogie 20 is detected as follows. When the vehicle bogie 20 stops at the bogie stop portion 115, the wheel contact portion 119a of the lever member 119 is pressed from above by the wheel 21 of the vehicle bogie 20. When the wheel contact portion 119a is pressed, the lever member 119 rotates around the rotating shaft 1014 in the clockwise direction in FIG. 5 or FIG. 7, and the actuator operation portion 119b of the lever member 119 pushes up the actuator 1181 of the bogie detection sensor 118. The actuator 1181 is operated by being pushed up, and the bogie detection sensor 118 detects that the vehicle bogie 20 has been stopped by the bogie stopping portion 115 .

[0041] The bogie stopping portion 115 further includes a stopper device 40 for positioning the vehicle bogie 20. Fig. 9 is an E-E sectional view of Fig. 4, and is a diagram showing the configuration of the stopper device 40. Note that the wheels 21 shown by the two-dot chain line in Fig. 9 represent the position of the wheels 21 when the vehicle bogie 20 is stopped by the bogie stopping portion 115.

[0042] The stopper device 40 is made up of a pair of wheel stop members 41A, 41B, a pair of springs 42A, 42B (an example of an elastic member), and a pair of second air cylinders 43A, 43B. In the following, when describing matters common to the wheel stop members 41A, 41B, it will be simply called the wheel stop member 41, when describing matters common to the springs 42A, 42B, it will be simply called the spring 42, and when describing matters common to the second air cylinders 43A, 43B, it will be simply called the second air cylinder 43.

[0043] As shown in Fig. 9, the pair of wheel stop members 41 are arranged parallel to the rail 107A, sandwiching the lever member 119, and facing each other. The wheel stop member 41 is rotatably held by a rotating shaft 1016 to a support member 1015 erected on a base portion 1011, and is rotatable between a wheel stop position for positioning the vehicle bogie 20 and a retracted position where the wheels 21 of the vehicle bogie 20 can run. The wheel stop members 41A and 41B shown by solid lines in Fig. 9 are in the positioning position, and the wheel stop members 41A and 41B shown by two-dot chain lines are in the retracted position.

[0044] The wheel stop member 41 has a wheel abutment portion 411, which is positioned near the running surface 1071 of the rail 107A and opposed to the outer circumferential surface of the flange portion 21a of the wheel 21 when the wheel stop member 41 is in the wheel stop position. As a result, when the vehicle bogie 20 tries to move from the bogie stopping portion 115, the outer circumferential surface of the flange portion 21a of the wheel 21 abuts against the wheel abutment portion 411, preventing the vehicle bogie 20 from shifting out of position. On the other hand, when the wheel stop member 41 is in the retracted position, the wheel abutment portion 411 is retracted from the vicinity of the running surface 1071 of the rail 107A and does not abut against the wheel 21.

[0045] The wheel stop member 41 engages with the spring 42 and has an engagement pin 412 that engages with a rod 431 of the second air cylinder 43 .

[0046] One end of the spring 42 is engaged with the engagement pin 412, and the other end is fixed to a bracket 1017 fixed to the base 1011 closer to the lever member 119 than the support member 1015. When the wheel stop member 41 is rotated from the wheel stop position to the retracted position, the engagement pin 412 with which one end of the spring 42 is engaged is moved to the opposite side to the bracket 1017, and the spring 42 is stretched. As a result, the spring 42 exerts an elastic force on the engagement pin 412, urging the wheel stop member 41 to return to the wheel stop position. Note that the pair of wheel stop members 41A, 41B can rotate only in a direction in which one wheel contact portion 411 approaches the other wheel contact portion 411, and cannot rotate in the opposite direction.

[0047] In addition, the side end surface 413 of the wheel stop member 41 is positioned at an angle with respect to the running surface 1071 of the rail 107A when the wheel stop member 41 is located at the wheel stop position. In other words, it is positioned so that an uphill slope is formed from the second air cylinder 43 side toward the lever member 119 side. This side end surface 413 is a portion that comes into contact with the wheel 21 of the vehicle bogie 20 traveling on the rail 107A toward the bogie stopping portion 115. To explain in more detail, for example, when the vehicle bogie 20 traveling from the first bogie stopping portion 115A side is stopped at the second bogie stopping portion 115B, the third bogie stopping portion 115C, or the fourth bogie stopping portion 115D, the wheel 21 of the traveling vehicle bogie 20 first comes into contact with the wheel stop member 41A of the pair of wheel stop members 41A, 41B from the side opposite to the side facing the wheel stop member 41B. That is, the flange portion 21a of the wheel 21 contacts the side end surface 413 of the wheel stop member 41A. As the vehicle bogie 20 continues to travel after contacting the side end surface 413, the side end surface 413 is pressed against the flange portion 21a, and the wheel stop member 41A is rotated toward the retracted position against the elastic force of the spring 42A. As the wheel stop member 41A is rotated toward the retracted position, the wheel 21 can pass through the wheel stop member 41A. When the wheel 21 passes through the wheel stop member 41A, the wheel stop member 41A returns to the wheel stop position by the elastic force of the spring 42A, and sandwiches the wheel 21 together with the other wheel stop member 41B. This makes it possible to position the vehicle bogie 20 at the second bogie stop portion 115B, the third bogie stop portion 115C, or the fourth bogie stop portion 115D. Conversely, when the vehicle bogie 20 traveling from the fourth bogie stopping section 115D is stopped at the first bogie stopping section 115A, the second bogie stopping section 115B, or the third bogie stopping section 115C, the wheel 21 comes into contact with the side end face 413 of the wheel stop member 41B, so that the wheel stop member 41B is rotated by the wheel 21 toward the retracted position and then returns to the wheel stop position after the wheel 21 has passed.

[0048] Next, the second air cylinder 43 is disposed on the side of the wheel stop member 41 opposite to the spring 42 side, and its rod 431 is extendable in a direction parallel to the track direction of the rails 107A, 107B. The rod 431 is engaged with an engagement pin 412 of the wheel stop member 41 via an engagement member 432. When the wheel stop member 41 is in the wheel stop position, the amount of protrusion of the rod 431 is maximized. When the rod 431 is contracted from this state, the engagement pin 412 of the wheel stop member 41 is pulled by the rod 431 via the engagement member 432, so that the wheel stop member 41 can be rotated to the retracted position. Since the engaging member 432 has a slit 432a extending in a direction parallel to the track direction of the rails 107A, 107B, the engaging pin 412 of the wheel stop member 41, which rotates when the side end face 413 is pressed by the wheel 21 as described above, can move within the slit 432a toward the second air cylinder 43. Therefore, the wheel stop member 41 rotated by the wheel 21 does not apply a load to the rod 431 of the second air cylinder 43.

[0049] When the vehicle bogie 20 passes through the bogie stopping section 115, the wheel stop members 41 of the passing bogie stopping section 115 are positioned in the retracted position by the second air cylinder 43. For example, when the vehicle bogie 20 moves from the first bogie stopping section 115A toward the fourth bogie stopping section 115D, the vehicle bogie 20 passes through the second bogie stopping section 115B and the third bogie stopping section 115C. In this case, the wheel stop members 41 of the second bogie stopping section 115B and the third bogie stopping section 115C are rotated to the retracted position by the second air cylinder 43 so as not to interfere with the travel of the vehicle bogie 20.

[0050] The transport device 30, as shown in Figs. 4 to 7, comprises a transport cart 31 for running on the transport rails 110A, 110B, and a wheel holding member 32 for holding the wheels 21 of the vehicle cart 20.

[0051] The transport vehicle 31 is formed in a substantially rectangular flat plate shape, and each of the four corners is provided with a running wheel 311 and a guide roller 312. The running wheel 311 has a tread surface 311a that contacts the running surface 1101 of the transport rails 110A and 110B, and is used for the transport device 30 to travel on the transport rails 110A and 110B. The guide roller 312 is positioned so that the rotation axis is perpendicular to the step surface 101b, and the tread surface 312a can contact the opposing side walls 1102 of the transport rails 110A and 110B. As a result, when the transport device 30 travels on the transport rails 110A and 110B, the transport vehicle 31 is maintained in a position such that the longitudinal direction of the transport vehicle 31 is substantially aligned with the track direction of the transport rails 110A and 110B.

[0052] The transporting platform 31 engages with the first loop chain 114 rotated by the motor 113 on the back surface opposite to the step surface 101b. The first loop chain 114 is provided parallel to the transport rails 110A and 110B, and as shown in FIG. 8, both ends are wound around the sprockets 112A and 112B. The sprocket 112A on the motor 113 side is rotated by the second loop chain 160 rotated by the motor 113. The rotation of the sprocket 112A rotates the first loop chain 114. The rotation of the first loop chain 114 causes the transporting platform 31 engaged with the first loop chain 114 to travel on the transport rails 110A and 110B. This allows the transporting device 30 (transporting platform 31) to travel along the rails 107A and 107B parallel to the transport rails 110A and 110B.

[0053] In this way, the motor 113 and the first loop chain 114 provided on the base 101 allow the conveying device 30 itself to run without having power. Since the conveying device 30 does not have power, the size of the conveying device 30 can be reduced, and the movement space of the conveying device 30 can be minimized. Therefore, even if the height difference between the floor surface 101a (running surface 1071) and the step surface 101b is small, such as about 50 mm, it is possible to ensure sufficient movement space for the conveying device 30. In addition, since the conveying device 30 does not have power, it is not necessary to connect the conveying device 30 to a power source or a control device. The power source and the control device only need to be connected to the motor 113 provided on the base 101, and since they do not move like the conveying device 30, the wiring space can be minimized.

[0054] 4 and 6, the transport cart 31 has a sensor actuator 313 for activating the position detection sensors 117A, 117B, and 117C. The sensor actuator 313 is provided to protrude toward the rail 107A in a direction parallel to the sleeper direction, and straddles the transport guide rail 111 so that its tip can come into contact with the actuators 1171 of the position detection sensors 117A, 117B, and 117C. Since the sensor actuator 313 straddles the transport guide rail 111, the sensor actuator 313 passes above the transport guide rail 111 when the transport device 30 travels on the transport rails 110A and 110B.

[0055] Furthermore, the transporting platform 31 is provided with a bush member 314 on the front surface (the surface opposite to the back surface facing the step surface 101b) for holding the wheel holding member 32 so that the wheel holding member 32 can slide.

[0056] The wheel holding member 32 includes a flat base member 321 having a longitudinal direction in the track direction, and an engagement member 322 is provided at the longitudinal center of the base member 321, protruding toward the rail 107A in a direction parallel to the sleeper direction. A cylindrical engagement portion 323 is provided at the tip of the engagement member 322. The diameter of the engagement portion 323 is smaller than the width of the first guide groove 1111a of the fixed guide rail 1111 and the width of the second guide groove 1112a of the movable guide rail 1112, so that when the conveying device 30 travels on the conveying rails 110A and 110B, the engagement portion 323 can pass through the first guide groove 1111a of the fixed guide rail 1111 or the second guide groove 1112a of the movable guide rail 1112.

[0057] Then, when the conveyance device 30 stops at the carriage stop portion 115, the engaging portion 323 is positioned in the second guide groove 1112a of the movable guide rail 1112. That is, the engaging portion 323 is engaged with the rod 1161 of the first air cylinder 116 via the movable guide rail 1112. When the movable guide rail 1112 is moved from the first position to the second position in this engaged state, the side wall 1112c of the second guide groove 1112a on the first air cylinder 116 side presses the engaging portion 323, and moves the wheel holding member 32 from the first position to the second position. On the other hand, when the movable guide rail 1112 moves from the second position to the first position, the other side wall 1112b of the second guide groove 1112a presses the engaging portion 323, and moves the wheel holding member 32 from the second position to the first position. In other words, when the movable guide rail 1112 is slid by the first air cylinder 116, the wheel holding member 32 is also slid between the first position and the second position as the movable guide rail 1112 is slid.

[0058] A cylindrical arm member 324 is provided at each of both longitudinal ends of the base member 321 so as to protrude toward the rail 107B in a direction parallel to the sleeper direction. The arm member 324 is inserted into the through hole 314a provided in the above-mentioned bush member 314, thereby guiding the sliding movement of the wheel holding member 32. A holding member 325 for holding the wheel 21 of the vehicle bogie 20 is coupled to the tip of the arm member 324 on the rail 107B side. The holding member 325 is a roller having a rotation axis parallel to the sleeper direction.

[0059] When the wheel holding member 32 is in the second position, the pair of holding members 325 are positioned so as to sandwich the flange portion 21a at the lower end of the wheel 21 from both sides in the track direction (the position shown in Figs. 6 and 7). This position is for holding the wheel 21 of the vehicle bogie 20. When the transport device 30 (transport vehicle 31) travels with the pair of holding members 325 sandwiching the flange portion 21a from both sides in the track direction, the holding members 325 come into contact with the flange portion 21a of the wheel 21 and push the wheel 21 in the direction in which the transport device 30 (transport vehicle 31) travels. More specifically, for example, when the conveying device 30 (conveying carriage 31) travels from the first carriage stop section 115A toward the fourth carriage stop section 115D, the holding member 325 on the first carriage stop section 115A side (left side in the figure) abuts against the flange section 21a, and when the conveying device 30 travels in the opposite direction, the holding member 325 on the fourth carriage stop section 115D side (right side in the figure) abuts against the flange section 21a. This allows the vehicle carriage 20 to travel on the rails 107A and 107B and be conveyed. Note that the holding member 325 is a roller, and therefore can rotate with the rotation of the wheel 21, and damage to the wheel 21 caused by the holding member 325 abutting against the flange section 21a can be prevented.

[0060] Furthermore, when the wheel holding member 32 is in the first position, the holding member 325 is located at a position retreated from below the wheel 21, that is, at a position where the holding of the wheel 21 is released. In this state, when the transport device 30 travels, the holding member 325 does not come into contact with the flange portion 21a of the wheel 21, so that the transport device 30 does not transport the vehicle bogie 20 and travels independently.

[0061] As described above, the first air cylinder 116 provided in the carriage stop section 115 allows the conveying device 30 to hold and release the vehicle carriage 20 (wheels 21) even if the conveying device 30 itself does not have power. Since the conveying device 30 does not have power, the size of the conveying device 30 can be reduced, and the movement space of the conveying device 30 can be minimized. Therefore, even if the height difference between the floor surface 101a (running surface 1071) and the step surface 101b is small, such as about 50 mm, it is possible to ensure sufficient movement space for the conveying device 30. In addition, since the conveying device 30 does not have power, it is not necessary to connect the conveying device 30 to a power source or a control device. The power source and the control device only need to be connected to the first air cylinder 116 provided in the carriage stop section 115, and since they do not move like the conveying device 30, the wiring space can be minimized.

[0062] Next, the railway vehicle traverser 100 has side walls 102 that are raised vertically from both ends of the base 101 in the short side direction (left and right direction in FIG. 2). When the railway vehicle 10 or the vehicle bogie 20 is placed on the base 101, the side walls 102 are arranged on both sides of it. In other words, the rails 107 and the side walls 102 are positioned in a parallel relationship. In addition, a roof 103 is installed horizontally on the upper ends of the pair of side walls 102. This roof 103 is provided at a height that can cover the railway vehicle 10 pulled into the base 101, as shown in FIG. 2.

[0063] A pair of retraction mechanisms 120 for retracting the vehicle bogie 20 into the base 101 is attached to each of both end portions of the side wall portion 102 on the end opening 105 side. In this embodiment, a pair of retraction mechanisms 120 is provided at each of both end portions on the end opening 105 side, but it is also possible to provide only one pair on either side.

[0064] The retraction mechanism 120 is composed of a retraction arm 121 and a linear motion mechanism 122. The linear motion mechanism 122 has a linear guide rail 123 provided on the side wall portion 102, a loop chain 127 disposed on the upper portion of the linear guide rail 123, and a linear motion base 126 that performs linear motion along the linear guide rail 123. The loop chain 127 is wound around a sprocket 127a, and the loop chain 127 rotates when the sprocket 127a is rotated by a driving device (e.g., a motor) (not shown). The linear motion base 126 is connected to the loop chain 127, and the rotation of the loop chain 127 enables the linear motion base 126 to perform linear motion along the linear guide rail 123.

[0065] The retractable arm 121 is rotatably supported by the support 125 on the linear motion base 126. In addition, a holding mechanism 121a for holding the vehicle bogie 20 is provided at one end of the retractable arm 121 (the end protruding outward from the railcar traverser 100). In addition, a counterweight 121b is provided at the other end of the retractable arm 121 to balance the weight with the holding mechanism 121a. Since the retractable arm 121 is rotatably supported by the support 125, the retractable arm 121 can advance and retreat so as to protrude and retract from the end openings 105 provided on both sides of the railcar traverser 100 in accordance with the linear motion of the linear motion base 126. In addition, by rotating the retractable arm 121 around the support 125, the vertical position of the holding mechanism 121a can be manually adjusted to any height.

[0066] The railway vehicle traverser 100 having the above-mentioned configuration traverses the vehicle bogie 20 as follows. For example, a case will be described in which four vehicle bogies 20 are traversed from a first inspection / repair rail to a second inspection / repair rail laid parallel to the first inspection / repair rail.

[0067] First, the rails 107A, 107B of the railway vehicle traverser 100 are aligned with the first inspection and repair rail in the sleeper direction, and then the vehicle bogie 20 is retracted from the first inspection and repair rail to the base 101 by the retraction mechanism 120 on the first bogie stopping unit 115A side. How the vehicle bogie 20 is actually retracted by the retraction mechanism 120 will be described with reference to Figs. 10 and 11. Fig. 10 shows a state in which the tip of the retraction arm 121 of the retraction mechanism 120 is inserted into the vehicle bogie 20 on the ground (for example, on the inspection and repair rail). Fig. 11 shows a state in which the vehicle bogie 20 has been retracted onto the base 101.

[0068] First, with the linear base 126 moved to the end of its travel, the retractable arm 121 is rotated around the support 125 to adjust the height of the holding mechanism 121a. This adjustment is performed manually. After adjusting the height of the holding mechanism 121a to a height that allows it to be connected to the vehicle bogie 20, the tip of the holding mechanism 121a is connected to the vehicle bogie 20. The connection method is assumed to use a hole (not shown) provided in the side beam of the vehicle bogie 20, and the tip of the holding mechanism 121a is inserted into the hole in the side beam to enable the vehicle bogie 20 to be towed by the retractable arm 121.

[0069] Since the height of the holding mechanism 121a can be changed by changing the angle of the retractable arm 121 using the support part 125 as described above, it is possible to insert the holding mechanism 121a while making fine adjustments into the holes provided in the side beams of the vehicle bogie 20. If there is no suitable hole in the vehicle bogie 20, it is preferable to attach a jig to the vehicle bogie 20 side so that it can be held by the holding mechanism 121a.

[0070] After the holding mechanism 121a and the vehicle bogie 20 are connected, the loop chain 127 is rotated by the driving device to move the linear motion base 126 toward the inside of the railcar traverser 100. Then, as shown in FIG. 11, the vehicle bogie 20 is pulled by the retractable arm 121 and placed on the tongue rail 108. Then, the linear motion base 126 is further moved toward the inside of the railcar traverser 100, and the vehicle bogie 20 is pulled until it reaches the first bogie stop section 115A. At this time, the transport device 30 with the wheel holding member 32 positioned at the first position is kept waiting at the first bogie stop section 115A. In addition, it is not necessarily necessary to keep the conveying device 30 waiting at the first bogie stopping section 115A. After the vehicle bogie 20 is stopped at the first bogie stopping section 115A, the conveying device 30 with the wheel holding member 32 positioned in the first position may be run to the first bogie stopping section 115A.

[0071] The vehicle bogie 20 that has reached the first bogie stopping portion 115A is positioned by the stopper device 40. When this positioning is achieved, the bogie detection sensor 118 of the first bogie stopping portion 115A detects that the vehicle bogie 20 has been stopped at the first bogie stopping portion 115A, and the first air cylinder 116 of the first bogie stopping portion 115A becomes operable. When the first air cylinder 116 is driven, the wheel holding member 32 is moved from the first position to the second position. When the wheel holding member 32 is positioned at the second position, the wheels 21 of the vehicle bogie 20 are held by the holding member 325.

[0072] With the wheels 21 of the vehicle bogie 20 held, the motor 113 is driven to make the transport device 30 travel toward the fourth bogie stopping section 115D. Since the wheel holding member 32 (holding member 325) holds the wheels 21, the vehicle bogie 20 travels on the rails 107A and 107B as the transport device 30 travels. The travel speed of the transport device 30 when transporting the vehicle bogie 20 is approximately 15 m / min at maximum.

[0073] When the sensor operation unit 313 of the conveyance device 30 traveling toward the fourth carriage stopping portion 115D operates the position detection sensor 117A of the fourth carriage stopping portion 115D, control is performed to reduce the rotation speed of the motor 113, and the travel speed of the conveyance device 30 is decelerated to approximately 3 m / min. When the sensor operation unit 313 of the decelerated conveyance device 30 further operates the position detection sensor 117B of the fourth carriage stopping portion 115D, the motor 113 is stopped and the conveyance device 30 is stopped at the fourth carriage stopping portion 115D.

[0074] At the same time that the conveying device 30 stops at the fourth bogie stopping section 115D, the vehicle bogie 20 reaches the fourth bogie stopping section 115D. The vehicle bogie 20 that has reached the fourth bogie stopping section 115D is positioned by the stopper device 40. Note that, since the vehicle bogie 20 passes through the second bogie stopping section 115B and the third bogie stopping section 115C before reaching the fourth bogie stopping section 115D, during this passage, the wheel stop members 41 of the stopper devices 40 of the second bogie stopping section 115B and the third bogie stopping section 115C are positioned in the retracted position.

[0075] In addition, when the conveyance device 30 travels toward the fourth carriage stop portion 115D, all the movable guide rails 1112 are positioned at the second position, and a series of grooves are formed by the first guide grooves 1111a of the fixed guide rails 1111 and the second guide grooves 1112a of the movable guide rails 1112. As a result, while the conveyance device 30 is traveling, the engagement portion 323 of the conveyance device 30 passes through the series of grooves. Then, when the conveyance device 30 reaches the fourth carriage stop portion 115D, the engagement portion 323 is engaged with the second guide grooves 1112a of the movable guide rails 1112 located at the fourth carriage stop portion 115D.

[0076] When the vehicle bogie 20 is positioned at the fourth bogie stopping section 115D, the bogie detection sensor 118 of the fourth bogie stopping section 115D detects that the vehicle bogie 20 has been stopped at the fourth bogie stopping section 115D, and the rod 1161 of the first air cylinder 116 is driven. As a result, the movable guide rail 1112 with which the engaging portion 323 is engaged is moved from the second position to the first position, and the wheel holding member 32 is moved from the second position to the first position. When the wheel holding member 32 is located at the first position, the holding of the wheels 21 of the vehicle bogie 20 by the holding member 325 is released, and the transportation of the vehicle bogie 20 is completed.

[0077] To further transport a second vehicle bogie 20, the second vehicle bogie 20 is stopped at the first bogie stopping section 115A using the retraction mechanism 120, and the transport device 30 is returned to the first bogie stopping section 115A by the first drive device. Note that either stopping the second vehicle bogie 20 at the first bogie stopping section 115A or returning the transport device 30 to the first bogie stopping section 115A may be performed first.

[0078] When returning the conveying device 30 to the first bogie stop section 115A, the movable guide rail 1112 located at the first bogie stop section 115A is moved to the first position because it was in the second position when the first vehicle bogie 20 was held. And, the movable guide rail 1112 located at the fourth bogie stop section 115D is in the first position when the first vehicle bogie 20 is released from the hold, so when the conveying device 30 is made to travel toward the first bogie stop section 115A in this state, the engagement portion 323 of the conveying device 30 passes near the side surface 1111b of the fixed guide rail 1111 on the rail 107A side without passing through the first guide groove 1111a. In addition, since each of the movable guide rails 1112 located at the second bogie stop portion 115B and the third bogie stop portion 115C is located at the second position, the engagement portion 323 does not pass through the second guide groove 1112a, but passes near the side surface of the movable guide rail 1112 on the rail 107A side. Then, when the conveying device 30 reaches the first bogie stop portion 115A, the movable guide rail 1112 located at the first bogie stop portion 115A is located at the first position as described above, so that the engagement portion 323 is engaged with the second guide groove 1112a of the movable guide rail 1112 located at the first bogie stop portion 115A. As a result, by driving the first air cylinder 116 of the first bogie stop portion 115A, the wheel holding member 32 can be moved from the first position to the second position, and the wheel 21 of the second vehicle bogie 20 can be held.

[0079] Then, when the conveying device 30 is moved to the third bogie stopping portion 115C, the second vehicle bogie 20 is positioned at the third bogie stopping portion 115C by the stopper device 40 of the third bogie stopping portion 115C. Furthermore, the engaging portion 323 of the conveying device 30 is engaged with the second guide groove 1112a of the movable guide rail 1112 located at the third bogie stopping portion 115C. Therefore, when the first air cylinder 116 of the third bogie stopping portion 115C is driven, the wheel holding member 32 can be moved from the second position to the first position, and the holding of the wheel 21 is released. This completes the conveying of the second vehicle bogie 20.

[0080] Furthermore, to transport the third vehicle bogie 20, the third vehicle bogie 20 is stopped at the first bogie stopping section 115A using the retraction mechanism 120, and the transport device 30 is returned to the first bogie stopping section 115A by the first drive device. Note that either stopping the third vehicle bogie 20 at the first bogie stopping section 115A or returning the transport device 30 to the first bogie stopping section 115A may be performed first.

[0081] When returning the transport device 30 to the first carriage stop section 115A, the movable guide rail 1112 located at the first carriage stop section 115A is moved to the first position in the same manner as when transporting the second vehicle carriage 20. Since the movable guide rail 1112 located at the third carriage stop section 115C is in the first position when the second vehicle carriage 20 is released from the hold, when the transport device 30 is made to travel toward the first carriage stop section 115A in this state, the engagement portion 323 of the transport device 30 passes near the side surface of the fixed guide rail 1111 on the rail 107A side without passing through the first guide groove 1111a. Moreover, since the movable guide rail 1112 located at the second carriage stop section 115B is located at the second position, the engagement portion 323 passes near the side surface of the movable guide rail 1112 on the rail 107A side without passing through the second guide groove 1112a. Then, when the conveying device 30 reaches the first bogie stopping portion 115A, the movable guide rail 1112 located at the first bogie stopping portion 115A is in the first position, so that the engaging portion 323 engages with the second guide groove 1112a of the movable guide rail 1112 located at the first bogie stopping portion 115A. As a result, by driving the first air cylinder 116 of the first bogie stopping portion 115A, the wheel holding member 32 can be moved from the first position to the second position, and the wheels 21 of the third vehicle bogie 20 can be held.

[0082] Then, when the conveying device 30 is moved to the second bogie stop portion 115B, the third vehicle bogie 20 is positioned at the second bogie stop portion 115B by the stopper device 40 of the second bogie stop portion 115B. Furthermore, the engagement portion 323 of the conveying device 30 is engaged with the second guide groove 1112a of the movable guide rail 1112 located at the second bogie stop portion 115B. Therefore, when the first air cylinder 116 of the second bogie stop portion 115B is driven, the wheel holding member 32 can be moved from the second position to the first position, and the holding of the wheel 21 is released. This completes the conveyance of the third vehicle bogie 20. Then, when the last, fourth vehicle bogie 20 is stopped at the first bogie stop portion 115A using the retraction mechanism 120, the loading is completed.

[0083] In the above description, the vehicle bogie 20 is pulled into the base 101 by using the pulling mechanism 120 on the first bogie stopping portion 115A side, and the vehicle bogie 20 is pulled into the base 101 by using the fourth bogie stopping portion 115D, The vehicle bogie 20 is stopped in the order of the third bogie stopping unit 115C, the second bogie stopping unit 115B, and the first bogie stopping unit 115A, but it is also possible to use the retraction mechanism 120 on the fourth bogie stopping unit 115D side to retract the vehicle bogie 20 into the base 101 and stop the vehicle bogie 20 in the order of the first bogie stopping unit 115A, the second bogie stopping unit 115B, the third bogie stopping unit 115C, and the fourth bogie stopping unit 115D.

[0084] After the vehicle bogie 20 is stopped at each of the first bogie stopping section 115A, the second bogie stopping section 115B, the third bogie stopping section 115C, and the fourth bogie stopping section 115D, the railway vehicle traverser 100 is caused to run on the lateral travel rail 150. Then, the railway vehicle traverser 100 is stopped at a position where the rails 107A, 107B of the railway vehicle traverser 100 and the second inspection and repair rail are aligned in the lateral direction, and the vehicle bogie 20 is lowered from the railway vehicle traverser 100 to the second inspection and repair rail.

[0085] To remove the vehicle bogie 20 from the railcar traverser 100, for example, first, the vehicle bogie 20 stopped at the fourth bogie stopping section 115D is pulled to the end opening 105 of the railcar traverser 100 using the retraction mechanism 120 on the fourth bogie stopping section 115D side, and removed from the railcar traverser 100. Then, the vehicle bogie 20 stopped at the third bogie stopping section 115C is transported to the fourth bogie stopping section 115D using the transport device 30, and then, using the retraction mechanism 120, is pulled to the end opening 105 and removed from the railcar traverser 100. The vehicle bogie 20 stopped at the second bogie stopping section 115B and the vehicle bogie 20 stopped at the first bogie stopping section 115A are also transported in sequence to the fourth bogie stopping section 115D using the transport device 30, and then pulled to the end opening 105 using the retraction mechanism 120, and removed from the railway vehicle traverser 100. As described above, the traverse is completed by removing the four vehicle bogies 20 from the railway vehicle traverser 100. Note that it is also possible to remove the vehicle bogies 20 in order, starting from the vehicle bogie 20 stopped at the first bogie stopping section 115A, instead of removing the vehicle bogies 20 stopped at the fourth bogie stopping section 115D.

[0086] As described above, according to the railway vehicle traverser 100 of this embodiment, (1) A rail vehicle traverser 100 includes a base 101 for mounting a vehicle bogie 20, the base 101 including rails 107A, 107B on which the vehicle bogie 20 can run, and a plurality of bogie stopping sections 115 provided along the rails 107A, 107B, and the rail vehicle traverser 100 transports the vehicle bogie 20 stopped at the bogie stopping sections 115. The rail vehicle traverser 100 is movable along the rails 107A, 107B, and includes a conveying device 30 for causing the vehicle bogie 20 to run along the rails 107A, 107B, and the conveying device 30 includes a wheel holding member for holding the wheels 21 of the vehicle bogie 20. 32, the wheel holding member 32 being movable between a first position where the wheel 21 is released from the holding and a second position where the wheel 21 is held, the base 101 being equipped with a first drive device (e.g., a motor 113 and a first loop chain 114) for moving the conveying device 30 along the rails 107A, 107B, and the carriage stopping portion 115 being equipped with a second drive device (e.g., a first air cylinder 116) for moving the wheel holding member 32 of the conveying device 30 positioned at the carriage stopping portion 115 between the first position and the second position.

[0087] (2) In the railway vehicle traverser 100 described in (1), the second drive device (e.g., the first air cylinder 116) is provided with an operating axis (e.g., a rod 1161) capable of linear motion, the wheel holding member 32 is provided with an engagement portion 323 that engages with the operating axis (rod 1161), and when the conveying device 30 is positioned at the bogie stop portion 115, the engagement portion 323 engages with the operating axis (rod 1161), and this engagement enables the second drive device (e.g., the first air cylinder 116) to move the wheel holding member 32 between the first position and the second position.

[0088] (3) In the railway vehicle traverser 100 described in (1) or (2), the bogie stopping portion 115 is provided with a stopper device 40 that positions the vehicle bogie 20, the stopper device 40 is provided with a pair of wheel stop members 41 arranged parallel to and facing the rails 107A and 107B, each of the pair of wheel stop members 41 is movable between a wheel stop position where it is located near the running surfaces 1071 of the rails 107A and 107B and can contact the wheels 21, and a retracted position where it is retracted from the vicinity of the running surfaces 1071 of the rails 107A and 107B and cannot contact the wheels 21, the stopper device 40 is provided with an elastic member (e.g., a spring 42) that urges each of the pair of wheel stop members 41 to be positioned at the wheel stop position, and the rails are moved toward the bogie stopping portion 115. When a wheel 21 of the vehicle bogie 20 traveling on the wheels 107A, 107B comes into contact with one of the pair of wheel stop members 41 from the side opposite to the side facing the other wheel stop member 41 (side end surface 413), the one wheel stop member 41 is pressed by the wheel 21 of the vehicle bogie 20 heading toward the bogie stopping section 115, and is moved toward the retracted position against the elastic force of an elastic member (e.g., a spring 42), allowing the wheel 21 to pass through the one wheel stop member 41, and when the wheel 21 passes through the one wheel stop member 41, the one wheel stop member 41 returns to the wheel stop position due to the elastic force of the elastic member (e.g., a spring 42), and clamps the wheel 21 together with the other wheel stop member 41, positioning the vehicle bogie 20 at the bogie stopping section 115.

[0089] According to the railway vehicle traverser 100 having the above features, the transport device 30 is moved along the rails 107A, 107B by a first drive device (e.g., a motor 113 and a first loop chain 114) provided on the base 101. Furthermore, the transport device 30 is provided with a wheel holding member 32 for holding the wheels 21 of the vehicle bogie 20, and the wheel holding member 32 is moved between a first position where the wheel 21 is released from the holding and a second position where the wheel 21 is held by a second drive device (e.g., a first air cylinder 116) provided on the bogie stop unit 115.

[0090] That is, the conveying device 30 itself does not have any power. Since the conveying device 30 does not have power, the size of the conveying device 30 can be reduced. Therefore, it is possible to minimize the space required for movement. In addition, since the conveying device 30 does not have power, it is not necessary to connect the conveying device 30 to a power source or a control device. The power source and the control device can be connected to the first drive device (e.g., the motor 113) provided on the base 101 and the second drive device (e.g., the first air cylinder 116) provided on the bogie stop unit 115, and since these do not move like the conveying device 30, it is possible to minimize the space required for wiring. By providing the railroad vehicle traverser 100 with the space-saving conveying device 30 that minimizes the space required for movement and the space required for wiring, it is possible to automatically run the vehicle bogie 20 along the rails 107A and 107B. If it becomes possible for the vehicle bogie 20 to automatically run along the rails 107A, 107B, there will be no need to use human labor to transport the vehicle bogie 20 on the railway vehicle traverser 100, thereby ensuring the safety of workers.

[0091] The above embodiment is merely an example and does not limit the present invention in any way. Therefore, the present invention can be improved and modified in various ways without departing from the scope of the present invention. For example, the motor 113 and the first loop chain 114 are exemplified as the first drive device, but other linear motion mechanisms can be used. In addition, the number of carriage stops 115 provided on the base 101 is four, but the number is not limited to four and can be increased or decreased. [Explanation of symbols]
